ActiveSupport::EncryptedFile writes contents that will be encrypted to a temporary file. The temporary file's permissions are defaulted to the user's current `umask` settings, meaning that it's possible for other users on the same system to read the contents of the temporary file. Attackers that have access to the file system could possibly read the contents of this temporary file while a user is editing it. All users running an affected release should either upgrade or use one of the workarounds immediately.

There is a vulnerability in ActiveSupport if the new bytesplice method is called on a SafeBuffer with untrusted user input.

A regular expression based DoS vulnerability in Active Support <6.1.7.1 and <7.0.4.1. A specially crafted string passed to the underscore method can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability.

active-support ruby gem 5.2.0 could allow a remote attacker to execute arbitrary code on the system, caused by containing a malicious backdoor. An attacker could exploit this vulnerability to execute arbitrary code on the system.
